TurboSnail8898,
We are always trying to improve our products and I would like to get your feedback on where you feel our RC skimmers fall short when comparing them to H&S' external models.
I appreciate any constructive criticism you can offer.

Jeff, good to see you are looking for ways to improve the products.
My $0.02
One area that I see is pump mounting. H&S and Deltec have glued in fittings, and ER uses Uniseals. H&S has that very sturdy band that runs around the body. Although I have never heard of it happening, the idea of an external skimmer and a uniseal popping loose would be a real mess.
Another area where ER gets dinged around here compared to the German brands is performance. I'm not saying I agree with this assumption, and generally think the performance differences are overstated. This is a more difficult area since there is really no objective testing done to prove one way or another what the differences are.
Take an RS250, AP851, A200-1260. They all have very similar specs and are very close in price. What would be the incentive to buy an ER over the H&S?
Now move to the RC500 Vs the A300 3x1260 and AP703. Again, all 3 skimmers have very similar specs, but the RC500 is $540 less than the H&S and $1500 less than the Deltec! It would seem the ER is far and away a better skimmer for the $. The problem is, when a comparison is made, the general perception is the ER does not perform as well as the other brands even though there is no testing to prove performance one way or the other.
In the above examples with skimmers using similar pumps, similar body sizes, how does your neck diameter, pump location, input/output location and sizes etc stack up to the competition? Are they optimized for maximum performance?
One other thing that I have mentioned before. You have a hole in the product line. You dont have a 10" 2 pump skimmer.
